To all whom it may concern.

Be it known that I, LAwnnNon W. LUEL- LEN, a citizen of the United States, residing at Mountain Lakes, county of Morris, and State of New Jersey, have invented certain new and useful Improvements in Rece tacles, of which the following is a specification.

This invention relates to receptacles and particularly to cups or containers of paper or other light and fragile material and it is designed to provide a temporary vessel which While strong and serviceable can be very cheaply constructed, so that it may be economically discarded after a single use. Such receptacles have in recent years come in to quite general use as drinking cups for use in public places and have met with high approval from medical authorities as providing the only safe 'and satisfactory substitute for the dangerous common public drinking cup. The present invention provides an improved structure, which is strong and convenient, comfortable to drink from and. in which a plurality of cups can be stacked in properly spaced nested relation so as to beplaced within and readily delivered from a dispensing device. At the same time a very light material can be utilized for making the receptacle so that the cost of the same is low and permitting the receptacle to be easily crushed or destroyed by the user so as to prevent its being again employed. For the latter purpose the receptacle may also be so constructed that it w1ll be self-destructible and will become useless at a suitable interval after it has been first filled with the liquid which it is designed to contain.

In the accompanying drawing which forms a part of this 'specification I Figure 1 is a side elevation of a cup e bodying one form of the invention;

Fig. 2 is a vertical section through the cup on an enlarged scale;

or otherwse joining its ed es. The bottom of the cup is formed of a isk 3, preferably of paper or paste board somewhat heavier than the side wall 2. This bottom is secured in position, in some suitable manner, preferably as shown in Figs. 2 and 4. In practice the bottom is forced into the truncated cone until it fits tightly therein and stretches the paper outwardly around itsedges as indicated at 4, the bottom being thus partly held in position by the tension of the side wall. 'The lower edge of the part 2 is then bent or spun u :inside of the side wall to form a leg'5. he upper edge of this leg is preferably curledOr turned outwardly under'the bottom disk 3, as indicated at 6 the leg thus serving as a support for the bottom disk. An inwardly projecting rib or crease 7 is then pressed in the side wall of the cup,-

above the bottom 3, so as to form a shoulder leg 5. The'leg 5- is preferably not folded closely against the downwardly projecting portion 8 of the side wall 2, but a space 9 is left between these parts. The edge of the curled over portion 6 preferably abuts against the side wall so as to hold the parts 5 and. 8 spaced apart. This construction provides a downwardly projecting tubular supporting flange at the bottom of the cup of great rigidity and permits the use of a .very light material for the side wall 2. This supporting flange not only provides a support for the'cup when in use, but serves the important function. of spacing the on s apart when nested as for shipment or to placed in a dispensing apparatus. The use of this flange when the cups are nested holds them relatively free from each other and prevents them from, becoming wedged into each other in a manner to interfere with their ready separation and also holds the upper edges of the cups in? regular spaced relation, so as to permit the rims of successive cups to be properly'engaged by the engaging or grippmg portions of the dispensing apparatus 1n a well understood manner. The hollow construction shown for this flange provides greater rigidity than if the leg 5 were simply bent back closely against the outer portion 8, does not require the use of additional stock, as where several thiclmesses ofv material are folded back and forth or rolledup into a tight roll and is v and thus effectually prevent the re-use of the bead and in fact permits the making of the flange .of any desired depth tosecure the most satisfactory spacing of the nested cups. Moreover, in the construction shown, while the bottom 3 is firmly held in position, is,

not locked to the side wall as in constructions where the bottom is pro ided with a flange which is rolled into a cad with the lower edge of the side wall, so thatwhen the cup is crushed after use the bottomwill be loosened or separated from the side wall cup. The hollow formation of the flange performs the further function of catching any slight leakage of the contents of the receptacle around the edge of the bottom disk, as such slight leakage as may occur will run down into the s ace between the side wall and leg 5 where t will do no harm, before it will run over the curved portion 6 and escape at the bottom of the cup in a manner to be noticeable; The cup shown is provided with a beaded upper edge, or rim, of novel construction, which will now be described. This novel beaded edge is preferably. used in connection with the novel bottom construction described, although it will be understood that either of these features may be separately embodied ina re- ;ceptacle without departing from the invention. Referring particularly to Figs. 2 and 3, it will be seen that the upper edge of the side wall of the cup is rolled over to form a curved lip or rolllO of comparatively large radius, the edge of this rolled over portion being bent up within the roll, as indicated at 1 1. This bent up portion is preferably given a slight reverse curvature, as indicated at 12, and its edge caused to abut.

against the under-side of the roll 10. This construction provides a smooth roll edge, which is attractive in appearance, comfortable to the lips of the user when. drinking from the cup and which gives the maximum of rigidity to the rim of the cup for the material employed. Ex erience has shown that the construction escribed is much stronger and stifl'er than where the edge of thecup is simply rolled over to form a roll of roll 10 and thus'braces the roll so as to prevent material change in the section there-- of. The several curvatures of the bead or roll mutually interact and brace each other so that the full strength of every portion of therimisutili ized. The' width Oren; 1-511 is much greater than can, be secured where 1 'thedpaper is attempted to be rolled into a soli ,bead and therefore a greater resistance to'distortion is secured than with such a construction. The present construction is also mucheasier to manufacture than a solid.

rolled bead.

The receptacle herein disclosed may be treated with. paraflin or other water-proofing or stiffening material if desired, but this is unnecessaryasthe parts of the vessel are firmly held together without the use of such material and the vessel'is sufiiciently rigid for satisfactory use, even though made of very light flexible stock. When the receptacle is to beemployed as an individual drinking clip, the use of not only adds to the cost of construction, but is objectionable for a temporary cup,

arafiin or other coating material is prefera ly avoided as it asit' invites the preservation of the same i i .for repeated use.' By formin the cup of uncoatedpaper' it is made sel destructible,

(for .within a few minutes after the cup is oncejiilled with liquid, the paper softens and -tiie cup becomes unfit for further use. This self-destructible feature of the receptacle may also be secured, whether the cup be made of uncoated, or-coated or water-proof material; by securing together the edges of the side-Wall or other parts of the cup with a a paste orhinder cap le of being softened or weakened by the material which. the receptacle isto contain. Thus in the form of the cup illustrated, by securing the edges of the paper 2 together by means of a suitable soluble binder, the seam can be made to open a short time after the cup has been once filled with water and thus the continued or repeated use of the' cup is absolutely prevented. In this manner the cup becomes when subjected to use self-destructible and it is with this meanin that I have used this term in the annexe claims. By properly selecting the paste, the period for which the cup can be rendered serviceable can be practlcally determined in advance.

.This principle is applicable 'to receptacles of any construction which are held in shape or in which parts are held together by a paste or binder.

It is obvious that the constructural features disclosed may be employed in receptacles of. other nature and form from that illustrated in the drawings.

Having thus described my invention what I claim as new and desire tosecure by Let ters Patent is:

1, As a new article of manufacture a paper cup having a rim comprising an outwardly rolled portion, the edge of which is .bent up within said roll and into engage- ,ment with the underside of thetop thereof.

2. As a new article of manufacture a nestable drinking cup having a side-wall portion within which, near the lower. end thereof, is fitted a bottom, the edge of said side-wall portion being bent up beneath said bottom to form a supportfiig leg therefor, said supporting leg being spaced from the side-wall so as to form a hollow supporting flange for the receptacle, said side-wall portion having a shoulder formed therein above said bottom for holding the same in place, and a rim at .the upper end of said sidewall portion comprising an outwardly rolled portion, the'edge of which is bent up with- 111 said roll and spaced from the outer surface of said side-wall portion.

3. A receptacle having a side wall portion within which, near the lower end thereof, is fixed a bottom, the edge of said side wall portion being turned inwardly to form a supporting flange for said bottom, said flange being transversely loop shaped, said side wall portion having a shoulder formed therein adjacent to said bottom for holding the same in lace, and a rim at the upper end of said side wall portion comprising an outwardly rolled portion, the edge of which is bent upon said wall and spaced from the outer surface of said side wall portion.

A receptacle comprising a body portion having a turned over edge, said edge having a transversely loop shaped formation, one side of said loop being substantially straight, while the opposite side is bowed inwardly, with the edge turned outwardly, whereby a yieldable supporting rim is formed at the point of closure of said loop.

5. A receptacle comprising a body-portion having a turned over edge, said edge having a transversely loop shaped formation, one' side of said loop being substantially straight, while the opposite side is bowed inwardly, with the edge turned outwardly, whereby a yieldable supporting rim is formed at the point of closure of said loop capable of sustaining a considerable downward pressure.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
